I would rather have an Adams reproduction than this Cooper that I've never heard of before. Both the original .44 and the .31 copy made by Massachusetts Arms in the 1850's.
But before those, I want a replica of the Remington New Model Police revolvers, which were 5 shot .36 caliber revolvers built on a smaller frame than the New Model Army.
But Centurion is on to something here because this Cooper is basically a DA/SA open top Colt style revolver. The only work that would need to be done is changing the hand, bolt, sear, and other internal parts; the exterior would essentially be the same and it's not like Pietta or Uberti make completely true and authentic replicas of cap and ball revolvers as none of their Colt replicas have progressive rifling.
I would be interested in a double action cap and ball revolver based off the Colt, but because they don't exist, I can't buy it. Not saying I would and as somebody already said, that tooling up costs money for something that won't sell too well.
Understand, the cap and ball replica market sells to people wanting replica military firearms, not what everyday people or police were carrying back then. Were that the case, pepperbox replicas would be currently made.
